Leave dumpdev, but kill the savecore variable. Thus, it's still off by default, but all you need is enabling dumpdev now. phk's old argument that savecore might inadvertendly fill up the disk no longer counts, savecore now correctly obeyes a `minfree' file, and we ship our systems with such a file that even has a reasonable default.
